The important processes which bring about recycling of carbon dioxide between the biotic and abiotic components of an ecosystem are all of the following except L
- A) photosynthesis
- B) respiration
- C) decay
- D) burning of fossil fuels
Correct Answer: A) photosynthesis
Explanation
The fossil fuels include coal, natural gas and the products from the fractional distillation of crude oil, such as petrol and diesel. When any fossil fuel is burned, one of the combustion products is carbon dioxide. This has led to an increase in the percentage of carbon dioxide in the air. Thus, burning of fossil fuels add carbon dioxide to the biome. The answer should be photosynthesis because the byproduct of photosynthesis is oxygen and not carbon dioxide.
